Disparities between African American and Caucasian men in prostate cancer (PCa) diagnosis and treatment in the United States have been well established, with significant racial disparities documented at all stages of PCa management, from differences in the type of treatment offered to progression-free survival or death. These disparities appear to be complex in nature, involving biological determinants as well as socioeconomic and cultural aspects. We present a review of the literature on racial disparities in the diagnosis of PCa, treatment, survival, and genetic susceptibility...

BACKGROUND: In the general population, prostate adenocarcinoma affects predominately older men. If fact, most current guidelines suggest that males over the age of 50 years should undergo prostate cancer screening. However, the clinical behavior and prognosis of prostate cancer in young adults is not well defined. The aim of this study was to evaluate the clinical behavior, pathological characteristics, and prognosis of prostate cancer in young adults. METHODS: We retrospectively reviewed the records of young patients (age, ≤50 years) in our hospital with prostate adenocarcinoma between 1997 and 2013...

INTRODUCTION: Testosterone deficiency (TD), also known as hypogonadism, is a condition affecting a substantial proportion of men as they age. The diagnosis and management of TD can be challenging and clinicians should be aware of the current literature on this condition. AIM: To review the available literature concerning the diagnosis and management of TD and to provide clinically relevant recommendations from the Fourth International Consultation for Sexual Medicine (ICSM) meeting...

A 68-year-old man developed a right femoral vein deep vein thrombosis and bilateral pulmonary embolism while receiving chemotherapy for stage IV prostate cancer. His creatinine at diagnosis is 1.4 mg/dL, with an estimated clearance of 63 mL/min. In patients with cancer, should low-molecular-weight heparin treatment be dosed according to weight, or adjusted using anti-Xa levels?

INTRODUCTION: ERG expression has been described as a frequent event in prostate cancer indicating poor prognosis and promoting oncogenesis. It has also been demonstrated in Ewing's sarcoma, acute myeloid leukemia and acute T-lymphoblastic leukemia but could not be found in other epithelial tumors, Hodgkin's or Non-Hodgkin's lymphoma. We aimed to analyze ERG expression in multiple myeloma, following an index case of a patient with metastases of unknown origin in the spine strongly expressing ERG, which were thought to be of prostatic origin but turned out to be plasmacytic lesions...

INTRODUCTION: There is a need for a precise and reliable imaging to improve the management of prostate cancer. In recent years the PET/CT with choline has changed the handling of prostate cancer in Europe, and it is commonly used for initial stratification or for the diagnosis of a biochemical recurrence, although it does not lack limitations. Other markers are being tested, including the ligand of prostate-specific membrane antigen (PSMA), that seems to offer encouraging prospects. The goal of this piece of work was to critically review the role of choline and PSMA PET/CT in prostate cancer...

INTRODUCTION: Men with low socioeconomic position experience higher mortality after a prostate cancer diagnosis compared to men with a higher socioeconomic position, however, the specific mediators of this association are unclear. We therefore evaluated the influence of potential mediators on the association between socioeconomic position, and prostate cancer-specific and all-cause death in prostate cancer patients. MATERIALS AND METHODS: We conducted a cohort study of prostate cancer patients in the Danish Diet, Cancer and Health study...

The existing clinical biomarkers for prostate cancer (PCa) diagnosis are far from ideal (e.g., the prostate specific antigen (PSA) serum level suffers from lack of specificity, providing frequent false positives leading to over-diagnosis). A key step in the search for minimum invasive tests to complement or replace PSA should be supported on the changes experienced by the biochemical pathways in PCa patients as compared to negative biopsy control individuals. In this research a comprehensive global analysis by LC-QTOF was applied to urine from 62 patients with a clinically significant PCa and 42 healthy individuals, both groups confirmed by biopsy...

OBJECTIVE: Prostate specific antigen (PSA), used for the early diagnosis of prostate cancer (PCa), is one of the best tumour markers known so far. However, in situations when PSA is between 2-10 ng/mL, which is named as grey zone, PSA falls short of distinguishing benign prostate diseases from PCa. On the other hand, it was demonstrated in many previous studies that microRNA (miRNA) could be a marker for cancer. Therefore, in this study, it was aimed to enhance the diagnostic power of PSA, especially with grey zone patients, by the use of miRNA...

BACKGROUND: Transrectal ultrasound-guided repeat needle biopsy (TUGRNB) is widely used for diagnosis of prostate cancer (PCa). However, significance of TUGRNB in Chinese population was rarely reported. A retrospective study was conducted to evaluate the significance of TUGRNB applied in prediction of PCa in Chinese population. MATERIALS AND METHODS: A total of 960 from January 2009 to December 2012 were included. Repeat needle biopsy rate and PCa positive detection rate were evaluated...

Rapid and reliable diagnosis of prostate cancer (PCa) is highly desirable as current used methods lack specificity. In addition, identification of PCa biomarkers that can classify patients into high- and low-risk groups for disease progression at early stage will improve treatment decision-making. Here, we describe a set of protein-combination panels in urinary extracellular vesicles (EVs), defined by targeted proteomics and immunoblotting techniques that improve early non-invasive detection and stratification of PCa patients...

Targeting the androgen receptor (AR) pathway prolongs survival in patients with prostate cancer, but resistance rapidly develops. Understanding this resistance is confounded by a lack of noninvasive means to assess AR activity in vivo. We report intracellular accumulation of a secreted antigen-targeted antibody (SATA) that can be used to characterize disease, guide therapy, and monitor response. AR-regulated human kallikrein-related peptidase 2 (free hK2) is a prostate tissue-specific antigen produced in prostate cancer and androgen-stimulated breast cancer cells...

Prostate cancer (PC) is the most common and the second leading cause of cancer-related death among American men. Early diagnosis is a prerequisite to improving therapeutic benefits. However, the current clinical biomarkers for PC do not reliably decipher indolent PC from other urogenital disorders. Thus, effective clinical intervention necessitates development of new biomarkers for early detection of PC. The present study aimed to identify the miRNA signature in organ-confined (Gleason Score 6) prostate tumors...

Purpose Evidence on overweight, obesity, and an increased risk of cancer continues to accumulate and was updated in the 2016 handbook on weight control from the International Agency for Research on Cancer (IARC). The underlying primary data, together with dose-response meta-analysis and, finally, pooled analysis of individual participant data, add insight into the relation between obesity and cancer risk and prognosis. We summarize the evidence for mortality from prostate cancer, hematologic malignancies, and kidney cancer...

The aim of this study was to evaluate risk factors for biochemical failure (BF) following permanent prostate seed (125)I brachytherapy for prostate cancer. The study reviewed the medical records of 607 patients with biopsy-proven prostate adenocarcinoma who were treated at Oulu University Hospital between 2001 and 2014. Clinical characteristics at diagnosis, treatment-related data and follow-up data were collected to identify potential risk factors for BF, which was defined using the Phoenix criteria [prostate-specific antigen (PSA) increase >2 µg/l from the PSA nadir concentration, which defined as the lowest PSA concentration observed after BT]...

Bone metastases are common in many advanced solid tumours, being breast, prostate, thyroid, lung, and renal cancer the most prevalent. Bone metastases can produce skeletal-related events (SREs), defined as pathological fracture, spinal cord compression, need of bone irradiation or need of bone surgery, and hypercalcaemia. Patients with bone metastases experience pain, functional impairment and have a negative impact on their quality of life. Several imaging techniques are available for diagnosis of this disease...

INTRODUCTION: Gastric cancer develops in a multistep progression and is determined by genetic and environmental factors. Over-expression of Alpha Methylacyl CoA Racemase (AMACR) is useful in diagnosis of prostate cancer. There is plenty of genetic alteration that occurs in gastric adenocarcinoma. The present study was planned to determine if AMACR can be used as a diagnostic marker in gastric adenocarcinoma similar to prostate cancer. AIM: To study the expression of AMACR in gastric adenocarcinoma and correlate its expression with density of Helicobacter pylori...

PURPOSE: Cancers often have considerable induction periods. This confers a risk of reverse causation bias in studies of cancer risk associated with drug use, as early symptoms of a yet undiagnosed cancer might lead to drug treatment in the period leading up to the diagnosis. This bias can be alleviated by disregarding exposure for some time before the cancer diagnosis (lag time). We aimed at assessing the duration of lag time needed to avoid reverse causation bias. METHODS: We identified all Danish patients with incident cancer between 2000 and 2012 (n = 353 087)...
